Ta'ZZ 'who'm t may concern: y

:Be itvknown that l', W'Tiimiaii KNoBLoeu,

. a-citizenof the United States` residing in l thereby efficient conductivity of energy.

the cityand conntyof Phiiadelphia,- State et Pennsylvania., have invented a new and useful Electric Storage Battery, of which the following is a' specification.

' My invention coni'preliends a novel pillar strap for storage batteries, and novel means for connecting the electrodes to the pillan strap. Heretofore the electrodes of storage batteries have been connected to the pillar strap by lead burning which in many cases does not produce the proper -contactbetween the electrodes and the pillar strap,

thereby lessening'the efficiency of the battery.

My. novel pillar strap carries' means under t-he'contro'l of the operator in the' assembly of the electrodes to the pillar strap te insure at all times a ,perfect contact and from the electrodes to the pillar strap.-

Another object of my invention is to pro vide a novel construct-ion of a pillar strap for electrodes whereby .the electrodes are dei 'and'contacting surfaces betiveen the pillar ."s'trap'and tifeelectrodes against the action of theelectrolyte. y n

Another object of my invention is-to de- *gice a novel pillar strap comprising a casfor inclosing the clampingmeans for connecting the electrodes tothe pillar straps.

l1 designates a sealingstrip preferably of lead for closing the open end of th'e chamber 8' after the clamping devices are'positioned therein. rlhe edge of the casing is pressed tightly against the sealing strip to .seal the recess and the devices contained therein from the electrolyte.

The casing 6 has formed therewith a terminal post 12 for outside electrical connection.

rlhe bottom wall 5 of the casing is provided with a plurality of apertures 13,' eX- tending through the tapered extension 14 integral with and converging downwardly i from the under surface of the bottom wall 5.`

15 designates an electrodelug, see Figs. 1 and il, and this lug is of novel design to coperate with the novel pilla-r strap l. rlhis lug 15 is provided with an apron 16 extending around the lug and comprising upwardly diverging walls 17 forming a tapered socket 18. The'upper edge 19 of the Walls 17 terminates below the upper end Q() of the lug l5. ln the assembly of the electrodes 2 to the pillar strap 1, the lugs 15 are inserted into the apertures 13 and through the recess 8, the upper edge 20 of the lugs extending into therecess 21 formed in the inner surface ofthe top wall 4. The extension 14 engages in the socket 18, while between the upper edges Q0 of the wallsY 17 and the under surface of the bottom wall 5 is placed a gasket 22 to prevent any leakage of the electrolyte into the casing 3. This assemblage of the electrodes to the pillar strap positions the electrodes parallel te; each other and vert-ical with respect. to the@ pillar strap. The clamping devices 10 forthe lugs 16 consist of angular wedge bars adapted to engage the opposite faces of that part of the lugs 16 which is positioned in the recess 8. The wedge bars are arranged in pairs between the lugs 15, and lhave their outer faces Qi provided with longitudinally extending cutting teeth adapted to cut into the faces of the lugs to provide a clean contact. The inner vertical toothed faces 25 of the wedges are disposed at Ian angle to the outer faces 2t. and 2G designates a pinion seated in a socket 27 in the bottom wall 6 of the casing. The pinion 2G is provided with a polygonal shaped perforation to receive a key 28 for actuating the pinion to move the wedges in opposite directions to expand them and cause their outer faces to tightly wedge against and cut into the faces of the lugs to form a perfect electrical connection, and also serve as an effectual binding means between the pillar strap and the. lugs of the, electrodes to hold thc electrodes to the pillar strap.

29 designates threaded openings in the than the lugs 15 of the electrodes in order nei-:mies

top Wall 4f of the casing. These casing permit a key to pass into' a recess 8 to operam the pinion 26.

After the Wedges have all been properly adjusted with respect to the lugs 15, threaded plugs 30 are screwed into the openings 29 to form a closure. The plugs 30 have an suitable formation to receive a Working too Referring now to Figs. 8, 9 and l0 of the drawings, another embodiment of my invention is shown in which the casing of the pillar strap and the lugs of the electrodes are similarly formed and loosely assembled together in the same manner as that shown in Figs; 1, 2, and 3. ln this embodiment a single locking or binding member 3] ,is employed consisting of a bar 32 provided With a plurality of integral -fingers 33 having obliquely beveled edges 34 at opposite sides. rllhe binding member is inserted into the recess 8 to engage between and cut into the lugs 15 to collectively bind the lugs to the pillar strap. The binding member 31- is preferably composed of a harder material that the oblique bevel edges 34 will readilyf cut into the surface*` of the lugs to securely bind the lugs to the pillar strap and form a perfect contact between the electrodes and the pillar strap.

The open end of the recess 8 is edectively sealed by pressing the edges of the casing against the sealing strip 11 which corresponds in construction 'and arrangement to that seen in other figures of the drawing.

rl`he electrodes 2 are connected to the pillar strap l which form a'common terminal for all the electrodes by .inserting the lugs 15 of the electrodes into the pertures 13 of the casing the upper portions 20 thereof engag- 105 ing inthe recesses Q1 while the extension 14: on the under surface of the casing` 3 engages in the socket 18 on the lugs. thus holding the electrodes parallel with each other and vertical with respect to the pillar strap.

The clamping devices 10 are then inserted in the recess 8 of the casing between that portion of the lugs 15 exposed in the recess. rihe sealing strip 11 is then placed in vthe front open end of the casing and pressure is 115 applied to the edges of the casingsurrounding the sealing strip to form a tight closure for the recess and the devices contained thereon. The electrodes 2 are now loosely assembled in the pillar stra-p. and the clamp- 120 ing devices l0 are in the casing. The operator manipulates the key Q8 to turn the pinion 26 of each pair of clamping wedges lo cause the cutting edges 24 of the wedges Q3 to cut into the lugs 15 of the electrodes to 125 form a clean cut contact surface between the clamping' device. l

i ln the embodiment seen in Figs. S, 9 and 10, the clamping means for the electrodes consists of the single. member 3l provided 130 with integral fingers and adapted to be inserted into the recess 8 between the lugs 15 'and pressed forwardly to cause the oblique Having thus described my invention what I.claim as new and desire to secure by Let- 1. yThe ycombination with a pillar strap consisting of a chambe'red casing having apertures in its bottom, of electrodes extending through said apertures and Ainto said chamber, and locking members positioned between -adjacent electrodesand of a mateyrialharder than that of said velectrodes and arranged to cut said electrodes when moved y to locked position.
